Software Engineer, AI Product + Agents San Francisco | OnSite WHAT WE DO Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered. Our mission is to make risk frictionless for the builders and operators shaping the physical world - protecting progress from concept through construction and into decades of operation. The infrastructure behind the AI boom - data centers, semiconductor fabs, renewable energy assets - has to be built and insured. But traditional carriers weren't built for this speed: - Complex commercial construction projects routinely wait weeks for a single quote - Legacy carriers rely on static applications and disconnected systems - Brokers chase carriers through calls, emails, and resubmissions We built Shepherd to solve that. Our AI performs the same underwriting workflows in seconds, and integrates real-time data from construction technology partners - Procore, Autodesk, OpenSpace, DroneDeploy, and others - to see risk as it actually exists, not just as it was reported on a static form. We're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. We're closing in on the first fully agentic submission in the industry - email in, price out, no human intervention until the last mile. With Shepherd, safety, speed, and quality no longer trade off against one another - they compound. We're building: - Faster decisions - Smarter, more accurate pricing - Better risk outcomes for insureds who invest in safer practices We're not just modernizing insurance products. We're building the risk infrastructure for the next

CPU Performance & Workload Analysis Architect, Platform Architecture Austin, United States of America Modern system-on-chip (SoC) designs have dramatically changed how hardware and software is developed. It is increasingly important to understand the concerns of software developers when designing hardware while it is also increasingly meaningful for software developers to understand how their applications can map efficiently to modern client and server hardware. Those who can understand both and prefer to live at the intersection of hardware and software are deeply valuable, especially to Apple. The Apple CPU Architecture and Performance Team is seeking highly motivated and self-driven engineers who want to live at this intersection, individuals who have or want to develop domain expertise in emerging areas like AI, individuals who have a high-level CPU architecture understanding and desire to work with a world class team for CPU, SoC, and software development. Are you deeply accountable for your work? Your passion for product ownership and track record of product development will prove critical to your success on our team. We drive advanced exploration for next generation CPU architectures. As a member of this team, you are the interface between the CPU team, system teams, and many software teams at Apple. We have a data driven approach that is focused on real user workloads (both existing and emerging) so your work will guide optimizations and the direction of future CPUs. At the same time, you will be working with software developers to optimize code for our CPU designs and roadmap.
